Split string with Javascript RegExp based on different character lengths

I have a string that looks like this:

"12345678ABCDEFGHIJKLMN2018/05/202018/05/30ABCD"

I want to split it based on n-sized lengths: 8 chars, 14 chars, 10 chars, 10 chars, 4 chars

So it would look like this:

12345678 (8 chars)

ABCDEFGHIJKLMN (14 chars)

2018/05/20 (10 chars)

2018/05/30 (10 chars)

ABCD (4 chars)

I know I could do this way: /(.{8})/ then split the string and continue /(.{14})/ and so on... But I was wondering if it is possible with on RegExp?

You could match the length' with groups.

The result of match contains the full match and the groups. To get only the groups, this solution takes a destructuring assignment to a sparse array with rest parameters ... for getting an array without the first element.

var string = "12345678ABCDEFGHIJKLMN2018/05/202018/05/30ABCD",
    [, ...result] = string.match(/^(.{8})(.{14})(.{10})(.{10})(.{4})$/);
    
console.log(result);
